Memory Corruption Vulnerability in Linux Kernel Affecting AMD Accelerated Parallel Processing

CVE-2026-23280

What is CVE-2026-23280?

A vulnerability in the Linux kernel related to the AMD accelerated parallel processing (accel/amdxdna) can lead to buffer overflow issues. An improper calculation of the user buffer size can result in an undersized memory allocation, potentially causing memory corruption. This flaw could be exploited to destabilize systems or execute malicious code. The vulnerability has been addressed by implementing validation checks using check_add_overflow() helpers to ensure accurate size calculations prior to memory allocation.
